Suggestions On Development and Utilization of Kaolin Mine From Kaolin Vertical Mill Manufacturer| Professional Kaolin Grinding Mill

Kaolin is mainly produced in the coal seam strata on the unconformity surface of the Permian Liangshan Formation and Permian Longtan Formation, and occurs in layers. The ores can be divided into hard kaolin and soft kaolin, and the main mineral components are kaolinite and hydrated kaolinite. In addition to the kaolinite group minerals, quartz, illite and other minerals are associated. As a manufacturer of kaolin mill, HCMilling(Guilin Hongcheng)'s kaolin vertical roller mill has been widely used and recognized in the global market. Here are some suggestions for the development and utilization of kaolin mine.

HLM series kaolin vertical roller mill

The kaolin in Danzhai County, Guizhou Province, China is carbonaceous clay rock with argillaceous texture, felt texture and micro bedding structure. The clay mineral content is relatively high, about 95%, which is in the form of fine phosphorus flakes, needles and fibers, with turbid surface and poor optical property. Many irregular quasi contemporaneous cracks are developed on the surface of the rock, which are filled with iron peat and formed by shrinkage after diagenesis. The kaolin in Majiang County has argillaceous structure, felt structure, local silty sand structure and micro bedding structure. The content of clay minerals is about 86%, which is similar to the structure of clay minerals in Danzhai County kaolin. There are fine clastic and dusty carbonaceous and ferritic components distributed in it. The content of debris is relatively high, about 8%. It is mainly composed of silty granular quartz and a small amount of feldspar and rock debris. The particles are well sorted, with poor roundness, about 0.01~0.10 mm in size. It is distributed in the clay ore aggregate along the bedding direction as a single or block aggregate. Kaolin vertical roller mill manufacturer learned that the kaolin in Longli County is iron bearing carbonaceous clay rock with argillaceous structure, felt structure and local patchy structure. The content of clay minerals is about 93%, which has a structure similar to that of clay minerals in Danzhai County kaolin. There are many carbonaceous minerals in it, which are distributed in fine dispersion, or along with dusty iron minerals, which are distributed at the edge of clay mineral aggregate in fine vein or lump shape.

Kaolin vertical roller mill manufacturer compared the analysis results with the physical and chemical properties of kaolin used in ceramics, paper making and coatings in the national standard GB/T14563-2020, it can be seen that the content of Al2O3 in Danzhai and Majiang kaolin is about 36.5%, the content of SiO2 is about 45%, the content of SO3 is less than 0.20%, and the content of Fe2O3 is 0.71%, which meets the physical and chemical properties requirements of kaolin used in ceramics, paper making and coatings industries. The content of TiO2 is about 2%, which is not in line with the requirements of ceramic industry, The whiteness is 37.3 and 31.4 respectively, which do not meet the requirements of the papermaking and coating industries.

To sum up, Danzhai and Majiang kaolins need to be purified to remove TiO2, which can be used as kaolin for ceramic industry, optical glass crucible, grinding wheel, electric porcelain, high-grade ceramic glaze, embryo, etc. After further decolorization and whitening, they can be used as kaolin for paper making and coating industry, and used as filler for processing paper coatings and coatings.

Longli kaolin is mainly composed of hydrated kaolin, which has strong mechanical, flame retardant and electrical properties, and can be used as flame retardant, rubber filler, battery materials, etc; In addition, its special nanotube structure, high specific surface area and biocompatibility make it a good carrier material for adsorbent, catalyst, drug loading, etc.

The development and utilization of kaolin mine can not do without the support of kaolin grinding mill equipment. HLM series kaolin vertical roller mill produced by HCMilling(Guilin Hongcheng) is an ideal equipment for the development and utilization of kaolin mine. It can process 80-2500 meshes of kaolin powder. If you have relevant requirements, please contact us for details of the equipment.
